The quick growth of vehicles is due to fast urbanization in mega cities during last decades. This phenomenon has serious impacts on air quality, as emission from mobile vehicles is the major source of air pollution. As a result, any attempt to reduce the emitted air pollutants is needed. This study aims at improving the fuel quality in transporting system with particular emphasis on taxis in Te...

The purpose of the paper is to construct a polyhedral Markov field in R in analogy with the planar construction of the original Arak (1982) polygonal Markov field. We provide a dynamic construction of the process in terms of evolution of two-dimensional multi-edge systems tracing polyhedral boundaries of the field in three-dimensional timespace. We also give a general algorithm for simulating G...
IgA ELISA testing for the initial treatment of .pylori infection, without alarming signs such as weight loss, blood-positive stool, palpable mass, etc. can be used. Approach has been designed based on the UBT test. Though accurate UBT testing for treatment and follow-up is better, but due to financial constraints, we would prefer to use this method.

A reversible, ergodic, Markov process taking values in the space of polygonally segmented images is constructed. The stationary distribution of this process can be made to correspond to a Gibbs-type distribution for polygonal random fields introduced by Arak and Surgailis and a few variants thereof, such as those arising in Bayesian analysis of such random fields. Extensions to generalized poly...
BACKGROUND AND PURPOSE Pakistan, during the last decade, has seen an extensive escalation in population growth, urbanization, and industrialization, together with a great increase in motorization and energy use. As a result, a substantial rise has taken place in the types and number of emission sources of various air pollutants. However, due to the lack of air quality management capabilities, t...
Air quality, like weather, can affect everyone, but responses differ depending on the sensitivity and health condition of a given individual. To help protect exposed populations, many countries have put in place real-time air quality nowcasting and forecasting capabilities. We present in this paper an optimal combination of air quality measurements and model outputs and show that it leads to si...
indoor environment. The most important include indoor pollutants, outdoor pollutants near the building, pollution transport through the ventilation system, air cleaning or filtration, and indoor climate (temperature and relative humidity). Many building materials, the furnishings and equipment, and the occupants and their activities are sources of indoor pollution. Following is a list of some o...
UNLABELLED Multiple linkages connect air quality and climate change. Many air pollutant sources also emit carbon dioxide (CO2), the dominant anthropogenic greenhouse gas (GHG). The two main contributors to non-attainment of U.S. ambient air quality standards, ozone (O3) and particulate matter (PM), interact with radiation, forcing climate change. PM warms by absorbing sunlight (e.g., black carb...
